Please visit this site for me. I'm having a little trouble with the explanation.
Note however that you can find a similar explanation in all textbooks, so I'm in no way questioning the validity of the information.
The average force that the wall exerts on the molecule is impulse/ time (N's second law). But the time they have made use of, is the time for a 'round trip'. Shouldn't it be the time taken for the collision?

But couldn't we then make use of the 'average' over a longer period; lets say two 'round trips'. In which case, we would obtain a duration of 4d/v. And a different final result.
Or have I misunderstood?
